METHOD FOR CONTROLLING ANTI SURGE OF AIR COMPRESSOR IN OXYGEN FACTORY FOR SMOOTHLY PRODUCING METAL GOODS BY PREVENTING AIR COMPRESSOR FROM BEING MECHANICALLY DAMAGED

摘要

PURPOSE: A method for controlling an anti surge of an air compressor in an oxygen factory is provided to smoothly produce metal goods by preventing an air compressor from being mechanically damaged and by allowing oxygen, nitride, and argon gas to be continuously produced. CONSTITUTION: A method for controlling an anti surge of an air compressor in an oxygen factory includes a step of changing an exhaust pressure signal, which is inputted through a pressure signal input unit of a pressure control unit(200), into a percent value and outputting the percent value. An opening degree of an intake valve, a differential pressure(103) and a temperature of an inlet section, and an exhaust pressure(104) are measured and tested through an automatic flow-rate establishing unit(300) having an anti surge line. A surge line and an anti surge line are drawn by connecting obtained coordinates with each other.
